IIRC, icecast allocates memory and resources dynamically, whereas shoutcast
allocates them up front, based on the maximum number of clients as
specified in the config.  So using the above example, shoutcast will use
15.5 MB of RAM *all the time*, whether you have 100 listeners or 1.  Having
said that, I don't know the per listener figure for icecast.

Oh and there are, I believe, win32 ports of icecast.
